Development Of Adaptive Login Security Using A Combination Of AES And Bcrypt On The Laravel Framework

Abstract

User authentication security remains a major challenge in web application development, particularly in facing threats such as brute force attacks, credential theft, and data breaches. Conventional login systems that rely solely on static hashing methods are considered insufficiently adaptive to evolving security threats. This study aims to develop an adaptive login system based on the Laravel framework by combining the Advanced Encryption Standard (AES) and Bcrypt algorithms to enhance authentication data security. AES is utilized for symmetric encryption of sensitive data, while Bcrypt is used for password hashing due to its strength and resistance to brute force attacks. The adaptive login system is also equipped with logic to detect suspicious login patterns, such as repeated login attempts, triggering special handling like additional verification or delay mechanisms. The implementation is carried out using Laravel due to its robust security management features and efficient development support. Test results show that the developed system provides dual protection for login data, increases resistance to attacks, and maintains good performance. Therefore, the combination of AES and Bcrypt in an adaptive login system on Laravel proves to be effective in enhancing user authentication security in modern web applications.
